Light with a continuous distribution of wavelength is passed through the cell. applications of this technique in food analysis, forensic science, medical diagnosis, medical science etc. The frequency will be shifted in much the same way that an observer on a moving train hears a shift in the frequency of the pitch of a ringing bell at a railroad crossing. The measured spectrum is identical to the radiation distribution expected from a blackbody, a surface that can absorb all the radiation incident on it. Tungsten filament lamps and Hydrogen-Deuterium lamps are most widely used and suitable light source as they cover the whole UV region. Raman spectroscopy is used in many varied fields – in fact, any application where non-destructive, microscopic, chemical analysis and imaging is required. By also measuring the absorbance at specific wavelength, the impurities can be detected. It is also employed in forensic analysis in civil and criminal analysis. Spectroscopy, primarily in the electromagnetic spectrum, is a fundamental exploratory tool in the fields of physics, chemistry, and astronomy, allowing the composition, physical structure and electronic structure of matter to be investigated at the atomic, molecular and … For example, if a light source with a broad band of wavelengths is directed at a vapour of atoms, ions, or molecules, the particles will absorb those wavelengths that can excite them from one quantum state to another. Absorption spectroscopy measures the loss of electromagnetic energy after it illuminates the sample under study. Home » Applications of Absorption Spectroscopy (UV, Visible) ... Chemical kinetics Kinetics of reaction can also be studied using UV spectroscopy. Identification of substance Infrared spectroscopy is used to establish whether a given sample or an organic substance is identical with another or not like : Alkanes, Alkenes, Alkynes, Aromatic ring etc. It is used in analytical chemistry, phytochemistry (plant chemistry), biological analysis, health care, andmedicine. Medical practitioners employ magnetic resonance imaging (MRI), a multidimensional NMR imaging technique, for diagnostic purposes. Spectroscopy is a very big field within Analytical Chemistry. Laser Spectroscopy . Similarly, light frequencies will be Doppler-shifted up or down depending on whether the light source is approaching or receding from the observer. In physics and chemistry spectroscopy is an often used anlytical technique to identify chemical compounds through the spectrum emitted from or absorbed by them.
